Which of the following is a proper way to declare and initialize a variable in Java? myInteger=100; char = 'a'; int myNumber=10; "Variable"

The correct answer is: $int\quad myNumber=10;$<br /><br />In Java, a variable must be declared with a specific data type, such as int, char, or String, and then initialized with a value. The declaration and initialization of a variable in Java is done using the following syntax:<br /><br />dataType variableName = value;<br /><br />In the given options, only the third option, $int\quad myNumber=10;$, follows the correct syntax for declaring and initializing a variable in Java. The variable "myNumber" is declared as an integer (int) and initialized with the value 10.<br /><br />The first option, $myInteger=100;$, is incorrect because it does not specify the data type for the variable "myInteger". The second option, char = 'a';, is also incorrect because it does not specify the name of the variable. The fourth option, "Variable", is not a valid declaration or initialization statement in Java.
